How to use the gas combustion module ?

Hello,

I will wish to use the gas combustion module but so far without success.
I tried to activate it as described in the practical user's guide, for example by changing the "Eddy-Break Up pre-mixed flame" section in the file usppmo.f90,
line "ippmod (icoebu)" to 0.
This change has enabled "Pulverised Coal" module in the "Code Saturn GUI".

With only the basics in Fortran I can not follow the correct procedure.

Can you orientate me, please, for the activation of this module ?

Thanks
